Planet Mars 4

On behalf of the organising committee, it is my pleasure to send out the attached announcement and welcome you all in joining us at the 4th workshop "Planet Mars", to be held in les Houches (France), on 20-25 October 2013. The goals of the workshop are to integrate the main results of both the recent Earth-based observations and the missions to Mars into a new global picture of Mars evolution. With the same spirit of the previous workshops, discussions among scientists of different disciplines will be encouraged and it is foreseen that they will help refine the scientific goals of the future missions to Mars.
